In his post-game press conference, when Tomlin was asked about the Todd Haley offense, and why it devolved as the season progressed, he stated that it "...wasn't effective enough for us to win."
He, then, went on to say that "We gotta coach, and play better than we did."
You can read into it what you want, but it sounds like Todd Haley might be the one that gets the axe, after this season. If Mike Tomlin, Ben Roethlisberger, and some of the other players don't want Haley, he's gone.

Tomlin deserves the Axe. It's not only the offense that has sucked, its been everything and coaching is a major part of the blame.
